Key result
COVID-19 pandemic is associated with fewer AMI admissions, delayed care, and potential excess mortality.
Why the study?
The difference in time delay and clinical outcomes in patients with STEMI or non-STEMI between the COVID-19 pandemic and pre-pandemic era had not been fully investigated in Korea.
Does presentation during the COVID-19 pandemic worsen time delays and clinical outcomes in patients with acute myocardial infarction?
Observational (n=598)
Does presentation during the COVID-19 pandemic worsen time delays and clinical outcomes in patients with acute myocardial infarction?
p-value: p=0.061
The COVID-19 pandemic was associated with reduced AMI admissions, time delays, and underuse of guideline-directed medical therapy, potentially leading to excess mortality in Korea.
Pandemic delays linked to higher non-STEMI mortality; hypothesis-generating for public messaging to avert future presentation delays.
BACKGROUND: It has been known that the fear of contagion during the coronavirus disease 2019 (COVID-19) creates time delays with subsequent impact on mortality in patients with acute myocardial infarction (AMI). However, difference of time delay and clinical outcome in patients with ST-segment elevation myocardial infarction (STEMI) or non-STEMI between the COVID-19 pandemic and pre-pandemic era has not been fully investigated yet in Korea. The aim of this study was to investigate the impact of COVID-19 pandemic on time delays and clinical outcome in patients with STEMI or non-STEMI compared to the same period years prior. METHODS: A total of 598 patients with STEMI (n = 195) or non-STEMI (n = 403) who underwent coronary angiography during the COVID-19 pandemic (February 1 to April 30, 2020) and pre-pandemic era (February 1 to April 30, 2017, 2018, and 2019) were analyzed in this study. Main outcomes were the incidence of time delay, cardiac arrest, and in-hospital death. RESULTS: = 0.061) during the pandemic. CONCLUSION: During the COVID-19 pandemic, there has been a considerable reduction in hospital admissions for AMI, time delay, and underuse of ACE-I/ARBs for the management of AMI, and this might be closely associated with the excess death in Korea.

Choi et al. (2022) conducted an observational in Acute Myocardial Infarction (STEMI or non-STEMI) (n=598). COVID-19 pandemic vs. Pre-pandemic era was evaluated on Incidence of time delay, cardiac arrest, and in-hospital death (p=0.061). The COVID-19 pandemic was associated with a considerable reduction in hospital admissions for AMI, time delay, and underuse of ACE-I/ARBs, potentially linked to excess death in Korea (P=0.061).
